CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 14/399,392, filed Nov. 6, 2014, which is a national stage filing under 35 U.S.C. § 371 of PCT/US2013/040080, filed May 8, 2013, which claims priority to U.S. Provisional Ser. No. 61/644,612, filed May 9, 2012, all of which are hereby incorporated by reference in their entirety.

BACKGROUND

Over 1.1 billion people worldwide are reported to be overweight. Obesity is estimated to affect over 90 million people in the United States alone. Twenty-five percent of the population in the United States over the age of twenty is considered clinically obese. While being overweight or obese presents problems (for example restriction of mobility, discomfort in tight spaces such as theater or airplane seats, social difficulties, etc.), these conditions, in particular clinical obesity, affect other aspects of health, i.e., diseases and other adverse health conditions associated with, exacerbated by, or precipitated by being overweight or obese. The estimated mortality from obesity-related conditions in the United States is over 300,000 annually (O'Brien et al. Amer J Surgery (2002) 184:4S-8S; and Hill et al. (1998) Science, 280:1371).

There is no curative treatment for being overweight or obese. Traditional pharmacotherapies for treating an overweight or obese subject, such as serotonin and noradrenergic re-uptake inhibitor, noradrenergic re-uptake inhibitors, selective serotonin re-uptake inhibitors, intestinal lipase inhibitors, or surgeries such as stomach stapling or gastric banding, have been shown to provide minimal short-term benefits or significant rates of relapse, and have further shown harmful side-effects to patients.

MetAP2 encodes a protein that functions at least in part by enzymatically removing the amino terminal methionine residue from certain newly translated proteins such as glyceraldehyde-3-phosphate dehydrogenase (Warder et al. (2008) J Proteome Res 7:4807). Increased expression of the MetAP2 gene has been historically associated with various forms of cancer. Molecules inhibiting the enzymatic activity of MetAP2 have been identified and have been explored for their utility in the treatment of various tumor types (Wang et al. (2003) Cancer Res 63:7861) and infectious diseases such as microsporidiosis, leishmaniasis, and malaria (Zhang et al. (2002) J Biomed Sci. 9:34). Notably, inhibition of MetAP2 activity in obese and obese-diabetic animals leads to a reduction in body weight in part by increasing the oxidation of fat and in part by reducing the consumption of food (Rupnick et al. (2002) Proc Natl Acad Sci USA 99:10730).

Such MetAP2 inhibitors may be useful as well for patients with excess adiposity and conditions related to adiposity including type 2 diabetes, hepatic steatosis, and cardiovascular disease (via e.g. by ameliorating insulin resistance, reducing hepatic lipid content, and reducing cardiac workload). Accordingly, compounds capable of modulating MetAP2 are needed to address the treatment of obesity and related diseases as well as other ailments favorably responsive to MetAP2 modulator treatment.

SUMMARY

The disclosure provides, for example, compounds which may be modulators of MetAP2, and their use as medicinal agents, processes for their preparation, pharmaceutical compositions containing them as an active ingredient both alone or in combination with other agents, to their use as medicaments and to their use in the manufacture of medicaments for the use in the inhibition of MetAP2 activity in warm-blooded animals such as humans. In particular this invention relates to compounds useful for the treatment of obesity, type 2 diabetes, and other obesity-associated conditions. Also provided are pharmaceutical compositions comprising at least one disclosed compound and a pharmaceutically acceptable carrier.

DETAILED DESCRIPTION

The features and other details of the disclosure will now be more particularly described. Before further description of the present invention, certain terms employed in the specification, examples and appended claims are collected here. These definitions should be read in light of the remainder of the disclosure and understood as by a person of skill in the art. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by a person of ordinary skill in the art.

Definitions

“Treating” includes any effect, e.g., lessening, reducing, modulating, or eliminating, that results in the improvement of the condition, disease, disorder and the like.

“Pharmaceutically or pharmacologically acceptable” include molecular entities and compositions that do not produce an adverse, allergic or other untoward reaction when administered to an animal, or a human, as appropriate. For human administration, preparations should meet sterility, pyrogenicity, general safety and purity standards as required by FDA Office of Biologics standards.

The term “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” as used herein refers to any and all solvents, dispersion media, coatings, isotonic and absorption delaying agents, and the like, that are compatible with pharmaceutical administration. The use of such media and agents for pharmaceutically active substances is well known in the art. The compositions may also contain other active compounds providing supplemental, additional, or enhanced therapeutic functions.

The term “pharmaceutical composition” as used herein refers to a composition comprising at least one compound as disclosed herein formulated together with one or more pharmaceutically acceptable carriers.

“Individual,” “patient,” or “subject” are used interchangeably and include any animal, including mammals, preferably mice, rats, other rodents, rabbits, dogs, cats, swine, cattle, sheep, horses, or primates, and most preferably humans. The compounds of the invention can be administered to a mammal, such as a human, but can also be administered to other mammals such as an animal in need of veterinary treatment, e.g., domestic animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, sheep, pigs, horses, and the like) and laboratory animals (e.g., rats, mice, guinea pigs, and the like). The mammal treated in the methods of the invention is desirably a mammal in which treatment of obesity, or weight loss is desired. “Modulation” includes antagonism (e.g., inhibition), agonism, partial antagonism and/or partial agonism.

In the present specification, the term “therapeutically effective amount” means the amount of the subject compound that will elicit the biological or medical response of a tissue, system, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician. The compounds of the invention are administered in therapeutically effective amounts to treat a disease. Alternatively, a therapeutically effective amount of a compound is the quantity required to achieve a desired therapeutic and/or prophylactic effect, such as an amount which results in weight loss.

The term “pharmaceutically acceptable salt(s)” as used herein refers to salts of acidic or basic groups that may be present in compounds used in the present compositions. Compounds included in the present compositions that are basic in nature are capable of forming a wide variety of salts with various inorganic and organic acids. The acids that may be used to prepare pharmaceutically acceptable acid addition salts of such basic compounds are those that form non-toxic acid addition salts, i.e., salts containing pharmacologically acceptable anions, including but not limited to malate, oxalate, chloride, bromide, iodide, nitrate, acetate, tartrate, oleate, fumarate, formate, benzoate, glutamate, methanesulfonate, benzenesulfonate, and p-toluenesulfonate salts.

The compounds of the disclosure may contain one or more chiral centers and/or double bonds and, therefore, exist as stereoisomers, such as geometric isomers, enantiomers or diastereomers. The term “stereoisomers” when used herein consist of all geometric isomers, enantiomers or diastereomers. These compounds may be designated by the symbols “R” or “S,” depending on the configuration of substituents around the stereogenic carbon atom. The present invention encompasses various stereoisomers of these compounds and mixtures thereof. Stereoisomers include enantiomers and diastereomers. Mixtures of enantiomers or diastereomers may be designated “(±)” in nomenclature, but the skilled artisan will recognize that a structure may denote a chiral center implicitly.

The compounds of the disclosure may contain one or more chiral centers and/or double bonds and, therefore, exist as geometric isomers, enantiomers or diastereomers. The enantiomer and diastereomers may be designated by the symbols “(+),” “(−).” “R” or “S,” depending on the configuration of substituents around the stereogenic carbon atom, but the skilled artisan will recognize that a structure may denote a chiral center implicitly. Geometric isomers, resulting from the arrangement of substituents around a carbon-carbon double bond or arrangement of substituents around a cycloalkyl or heterocyclic ring, can also exist in the compounds of the present invention. The symbol

denotes a bond that may be a single, double or triple bond as described herein. Substituents around a carbon-carbon double bond are designated as being in the “Z” or “E” configuration wherein the terms “Z” and “E” are used in accordance with IUPAC standards. Unless otherwise specified, structures depicting double bonds encompass both the “E” and “Z” isomers. Substituents around a carbon-carbon double bond alternatively can be referred to as “cis” or “trans,” where “cis” represents substituents on the same side of the double bond and “trans” represents substituents on opposite sides of the double bond. The arrangement of substituents around a carbocyclic ring can also be designated as “cis” or “trans.” The term “cis” represents substituents on the same side of the plane of the ring and the term “trans” represents substituents on opposite sides of the plane of the ring. Mixtures of compounds wherein the substituents are disposed on both the same and opposite sides of plane of the ring are designated “cis/trans.”

The term “stereoisomers” when used herein consist of all geometric isomers, enantiomers or diastereomers. The present invention encompasses various stereoisomers of these compounds and mixtures thereof.

Individual enantiomers and diasteriomers of compounds of the present invention can be prepared synthetically from commercially available starting materials that contain asymmetric or stereogenic centers, or by preparation of racemic mixtures followed by resolution methods well known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography and liberation of the optically pure product from the auxiliary, (2) salt formation employing an optically active resolving agent, (3) direct separation of the mixture of optical enantiomers on chiral liquid chromatographic columns or (4) kinetic resolution using steroselective chemical or enzymatic reagents. Racemic mixtures can also be resolved into their component enantiomers by well known methods, such as chiral-phase gas chromatography or crystallizing the compound in a chiral solvent. Stereoselective syntheses, a chemical or enzymatic reaction in which a single reactant forms an unequal mixture of stereoisomers during the creation of a new stereocenter or during the transformation of a pre-existing one, are well known in the art. Stereoselective syntheses encompass both enantio- and diastereoselective transformations. For examples, see Carreira and Kvaerno, Classics in Stereoselective Synthesis, Wiley-VCH: Weinheim, 2009.

The compounds disclosed herein can exist in solvated as well as unsolvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like, and it is intended that the invention embrace both solvated and unsolvated forms. In one embodiment, the compound is amorphous. In one embodiment, the compound is a polymorph. In another embodiment, the compound is in a crystalline form.

The invention also embraces isotopically labeled compounds of the invention which are identical to those recited herein, except that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl, respectively. For example, a compound of the invention may have one or more H atom replaced with deuterium.

Certain isotopically-labeled disclosed compounds (e.g., those labeled with ³H and ¹⁴C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ¹⁴C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence form a contemplated alternative embodiment. Isotopically labeled compounds of the invention can generally be prepared by following procedures analogous to those disclosed in the e.g., Examples herein by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.

Another aspect of this disclosure provides methods of modulating the activity of MetAP2. Such methods comprise exposing said receptor to a compound described herein. The ability of compounds described herein to modulate or inhibit MetAP2 can be evaluated by procedures known in the art and/or described herein. Another aspect of the invention provides methods of treating a disease associated with expression or activity of MetAP2 in a patient. For example, a contemplated method includes administering a disclosed compound in an amount sufficient to establish inhibition of intracellular MetAP2 effective to increase thioredoxin production in the patient and to induce multi organ stimulation of anti-obesity processes in the subject, for example, by administering a disclosed compound in an amount insufficient to reduce angiogenesis in the patient.

In certain embodiments, the disclosure provides a method of treating and or ameliorating obesity in a patient by administering an effective amount of a disclosed compound. Also provided herein are methods for inducing weight loss in a patient in need thereof.

Other contemplated methods of treatment include method of treating or ameliorating an obesity-related condition or co-morbidity, by administering a compound disclosed herein to a subject. For example, contemplated herein are methods for treating type 2 diabetes in a patient in need thereof.

Exemplary co-morbidities or other disorders that may be treated by a disclosed compound may include cardiac disorders, endocrine disorders, respiratory disorders, hepatic disorders, skeletal disorders, psychiatric disorders, metabolic disorders, metabolic disorders, and reproductive disorders.

Exemplary cardiac disorders include hypertension, dyslipidemia, ischemic heart disease, cardiomyopathy, cardiac infarction, stroke, venous thromboembolic disease and pulmonary hypertension. Exemplary endocrine disorders include type 2 diabetes and latent autoimmune diabetes in adults. Exemplary respiratory disorders include obesity-hypoventilation syndrome, asthma, and obstructive sleep apnea. An exemplary hepatic disorder is nonalcoholic fatty liver disease. Exemplary skeletal disorders include back pain and osteoarthritis of weight-bearing joints. Exemplary metabolic disorders include Prader-Willi Syndrome and polycystic ovary syndrome. Exemplary reproductive disorders include sexual dysfunction, erectile dysfunction, infertility, obstetric complications, and fetal abnormalities. Exemplary psychiatric disorders include weight-associated depression and anxiety.

In particular, in certain embodiments, the disclosure provides a method of treating the above medical indications comprising administering to a subject in need thereof a therapeutically effective amount of a compound described herein.

Obesity or reference to “overweight” refer to an excess of fat in proportion to lean body mass. Excess fat accumulation is associated with increase in size (hypertrophy) as well as number (hyperplasia) of adipose tissue cells. Obesity is variously measured in terms of absolute weight, weight:height ratio, distribution of subcutaneous fat, and societal and esthetic norms. A common measure of body fat is Body Mass Index (BMI). The BMI refers to the ratio of body weight (expressed in kilograms) to the square of height (expressed in meters). Body mass index may be accurately calculated using either of the formulas: weight (kg)/height² (m²) (SI) or 703×weight (lb)/height² (in²) (US).

In accordance with the U.S. Centers for Disease Control and Prevention (CDC), an overweight adult has a BMI of 25 kg/m² to 29.9 kg/m², and an obese adult has a BMI of 30 kg/m² or greater. A BMI of 40 kg/m² or greater is indicative of morbid obesity or extreme obesity. Obesity can also refer to patients with a waist circumference of about 102 cm for males and about 88 cm for females. For children, the definitions of overweight and obese take into account age and gender effects on body fat. Patients with differing genetic background may be considered “obese” at a level differing from the general guidelines, above.

The disclosed compounds may also be useful for reducing the risk of secondary outcomes of obesity, such as reducing the risk of left ventricular hypertrophy. Methods for treating patients at risk of obesity, such as those patients who are overweight, but not obese, e.g. with a BMI of between about 25 and 30 kg/m², are also contemplated. In certain embodiments, a patient is a human.

BMI does not account for the fact that excess adipose can occur selectively in different parts of the body, and development of adipose tissue can be more dangerous to health in some parts of the body rather than in other parts of the body. For example, “central obesity”, typically associated with an “apple-shaped” body, results from excess adiposity especially in the abdominal region, including belly fat and visceral fat, and carries higher risk of co-morbidity than “peripheral obesity”, which is typically associated with a “pear-shaped” body resulting from excess adiposity especially on the hips. Measurement of waist/hip circumference ratio (WHR) can be used as an indicator of central obesity. A minimum WHR indicative of central obesity has been variously set, and a centrally obese adult typically has a WHR of about 0.85 or greater if female and about 0.9 or greater if male.

Methods of determining whether a subject is overweight or obese that account for the ratio of excess adipose tissue to lean body mass involve obtaining a body composition of the subject. Body composition can be obtained by measuring the thickness of subcutaneous fat in multiple places on the body, such as the abdominal area, the subscapular region, arms, buttocks and thighs. These measurements are then used to estimate total body fat with a margin of error of approximately four percentage points. Another method is bioelectrical impedance analysis (BIA), which uses the resistance of electrical flow through the body to estimate body fat. Another method is using a large tank of water to measure body buoyancy. Increased body fat will result in greater buoyancy, while greater muscle mass will result in a tendency to sink.

In another aspect, the disclosure provides methods for treating an overweight or obese subject involving determining a level of at least one biomarker related to being overweight or obese in the subject, and administering an effective amount of a disclosed compound to achieve a target level in the subject. Exemplary biomarkers include body weight, Body Mass Index (BMI), Waist/Hip ratio WHR, plasma adipokines, and a combination of two or more thereof.

In some embodiments, disclosed compounds may not be available to a particular biotissue, which may result in fewer side effects (e.g., resulting in minimal or no involvement of other tissues such as the testes. For example, in some embodiments, compound A, upon administration, may have significantly less concentration in the testes as compared to concentration in the testes of a male patient of other MetAP-2 inhibitors (e.g. fumigillin (compound (i), or 201), or as compared to fumigillol derivatives such

(compound (ii), compound (iii)—fumigillol-compound 203, (iv)

(440); or compound 230:

upon administration.

The compounds of the invention may be administered to patients (animals (e.g. cats, dogs, and/or other companion animals or humans) in need of such treatment in dosages that will provide optimal pharmaceutical efficacy. It will be appreciated that the dose required for use in any particular application will vary from patient to patient, not only with the particular compound or composition selected, but also with the route of administration, the nature of the condition being treated, the age and condition of the patient, concurrent medication or special diets then being followed by the patient, and other factors which those skilled in the art will recognize, with the appropriate dosage ultimately being at the discretion of the attendant physician. For treating clinical conditions and diseases noted above, a compound of this invention may be administered orally, subcutaneously, topically, parenterally, by inhalation spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. Parenteral administration may include subcutaneous injections, intravenous or intramuscular injections or infusion techniques.

Treatment can be continued for as long or as short a period as desired. The compositions may be administered on a regimen of, for example, one to four or more times per day. A suitable treatment period can be, for example, at least about one week, at least about two weeks, at least about one month, at least about six months, at least about 1 year, or indefinitely. A treatment period can terminate when a desired result, for example a weight loss target, is achieved. A treatment regimen can include a corrective phase, during which dose sufficient to provide reduction of weight is administered, and can be followed by a maintenance phase, during which a e.g. over dose sufficient to weight gain is administered. A suitable maintenance dose is likely to be found in the lower parts of the dose ranges provided herein, but corrective and maintenance doses can readily be established for individual subjects by those of skill in the art without undue experimentation, based on the disclosure herein. Maintenance doses can be employed to maintain body weight in subjects whose body weight has been previously controlled by other means, including diet and exercise, bariatric procedures such as bypass or banding surgeries, or treatments employing other pharmacological agents.

Another aspect of the disclosure provides pharmaceutical compositions comprising compounds as disclosed herein formulated together with a pharmaceutically acceptable carrier. In particular, the present disclosure provides pharmaceutical compositions comprising compounds as disclosed herein formulated together with one or more pharmaceutically acceptable carriers. These formulations include those suitable for oral, rectal, topical, buccal, parenteral (e.g., subcutaneous, intramuscular, intradermal, or intravenous) rectal, vaginal, or aerosol administration, although the most suitable form of administration in any given case will depend on the degree and severity of the condition being treated and on the nature of the particular compound being used. For example, disclosed compositions may be formulated as a unit dose, and/or may be formulated for oral or subcutaneous administration.

Exemplary pharmaceutical compositions of this invention may be used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which contains one or more of the compound of the invention, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. The active ingredient may be compounded, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of the disease.

For preparing solid compositions such as tablets, the principal active ingredient may be mixed with a pharmaceutical carrier, e.g., conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g., water, to form a solid preformulation composition containing a homogeneous mixture of a compound of the invention, or a non-toxic pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.

In solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules and the like), the subject composition is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, the compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.

A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binder (for example, gelatin or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the subject composition moistened with an inert liquid diluent. Tablets, and other solid dosage forms, such as dragees, capsules, pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the subject composition, the liquid dosage forms may contain inert diluents commonly used in the art, such as, for example, water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, cyclodextrins and mixtures thereof.

Suspensions, in addition to the subject composition, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.

Formulations for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing a subject composition with one or more suitable non-irritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or a salicylate, and which is solid at room temperature, but liquid at body temperature and, therefore, will melt in the body cavity and release the active agent.

Dosage forms for transdermal administration of a subject composition includes powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active component may be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants which may be required.

The ointments, pastes, creams and gels may contain, in addition to a subject composition, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.

Powders and sprays may contain, in addition to a subject composition, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays may additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.

Compositions and compounds of the present invention may alternatively be administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation or solid particles containing the compound. A non-aqueous (e.g., fluorocarbon propellant) suspension could be used. Sonic nebulizers may be used because they minimize exposing the agent to shear, which may result in degradation of the compounds contained in the subject compositions. Ordinarily, an aqueous aerosol is made by formulating an aqueous solution or suspension of a subject composition together with conventional pharmaceutically acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular subject composition, but typically include non-ionic surfactants (Tweens, Pluronics, or polyethylene glycol), innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino acids such as glycine, buffers, salts, sugars or sugar alcohols. Aerosols generally are prepared from isotonic solutions.

Pharmaceutical compositions of this invention suitable for parenteral administration comprise a subject composition in combination with one or more pharmaceutically-acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.

Examples of suitable aqueous and non-aqueous carriers which may be employed in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate and cyclodextrins. Proper fluidity may be maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants

In another aspect, the invention provides enteral pharmaceutical formulations including a disclosed compound an enteric material; and a pharmaceutically acceptable carrier or excipient thereof. Enteric materials refer to polymers that are substantially insoluble in the acidic environment of the stomach, and that are predominantly soluble in intestinal fluids at specific pHs. The small intestine is the part of the gastrointestinal tract (gut) between the stomach and the large intestine, and includes the duodenum, jejunum, and ileum. The pH of the duodenum is about 5.5, the pH of the jejunum is about 6.5 and the pH of the distal ileum is about 7.5. Accordingly, enteric materials are not soluble, for example, until a pH of about 5.0, of about 5.2, of about 5.4, of about 5.6, of about 5.8, of about 6.0, of about 6.2, of about 6.4, of about 6.6, of about 6.8, of about 7.0, of about 7.2, of about 7.4, of about 7.6, of about 7.8, of about 8.0, of about 8.2, of about 8.4, of about 8.6, of about 8.8, of about 9.0, of about 9.2, of about 9.4, of about 9.6, of about 9.8, or of about 10.0. Exemplary enteric materials include cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), polyvinyl acetate phthalate (PVAP), hydroxypropyl methylcellulose acetate succinate (HPMCAS), cellulose acetate trimellitate, hydroxypropyl methylcellulose succinate, cellulose acetate succinate, cellulose acetate hexahydrophthalate, cellulose propionate phthalate, cellulose acetate maleat, cellulose acetate butyrate, cellulose acetate propionate, copolymer of methylmethacrylic acid and methyl methacrylate, copolymer of methyl acrylate, methylmethacrylate and methacrylic acid, copolymer of methylvinyl ether and maleic anhydride (Gantrez ES series), ethyl methyacrylate-methylmethacrylate-chlorotrimethylammonium ethyl acrylate copolymer, natural resins such as zein, shellac and copal collophorium, and several commercially available enteric dispersion systems (e. g., Eudragit L30D55, Eudragit FS30D, Eudragit L100, Eudragit S100, Kollicoat EMM30D, Estacryl 30D, Coateric, and Aquateric). The solubility of each of the above materials is either known or is readily determinable in vitro. The foregoing is a list of possible materials, but one of skill in the art with the benefit of the disclosure would recognize that it is not comprehensive and that there are other enteric materials that would meet the objectives of the present invention.

Advantageously, the invention also provides kits for use by a e.g. a consumer in need of weight loss. Such kits include a suitable dosage form such as those described above and instructions describing the method of using such dosage form to mediate, reduce or prevent inflammation. The instructions would direct the consumer or medical personnel to administer the dosage form according to administration modes known to those skilled in the art. Such kits could advantageously be packaged and sold in single or multiple kit units. An example of such a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process recesses are formed in the plastic foil. The recesses have the size and shape of the tablets or capsules to be packed. Next, the tablets or capsules are placed in the recesses and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are sealed in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed via said opening.

It may be desirable to provide a memory aid on the kit, e.g., in the form of numbers next to the tablets or capsules whereby the numbers correspond with the days of the regimen which the tablets or capsules so specified should be ingested. Another example of such a memory aid is a calendar printed on the card, e.g., as follows “First Week, Monday, Tuesday, . . . etc. . . . Second Week, Monday, Tuesday, . . . ” etc. Other variations of memory aids will be readily apparent. A “daily dose” can be a single tablet or capsule or several pills or capsules to be taken on a given day. Also, a daily dose of a first compound can consist of one tablet or capsule while a daily dose of the second compound can consist of several tablets or capsules and vice versa. The memory aid should reflect this.

Also contemplated herein are methods and compositions that include a second active agent, or administering a second active agent. For example, in addition to being overweight or obese, a subject or patient can further have overweight- or obesity-related co-morbidities, i.e., diseases and other adverse health conditions associated with, exacerbated by, or precipitated by being overweight or obese. Contemplated herein are disclosed compounds in combination with at least one other agent that has previously been shown to treat these overweight- or obesity-related conditions.

For example, Type II diabetes has been associated with obesity. Certain complications of Type II diabetes, e.g., disability and premature death, can be prevented, ameliorated, or eliminated by sustained weight loss (Astrup, A. Pub Health Nutr (2001) 4:499-5 15). Agents administered to treat Type II diabetes include sulfonylureas (e.g., Chlorpropamide, Glipizide, Glyburide, Glimepiride); meglitinides (e.g., Repaglinide and Nateglinide); biguanides (e.g., Metformin); thiazolidinediones (Rosiglitazone, Troglitazone, and Pioglitazone); dipeptidylpeptidase-4 inhibitors (e.g., Sitagliptin, Vildagliptin, and Saxagliptin); glucagon-like peptide-1 mimetics (e.g., Exenatide and Liraglutide); and alpha-glucosidase inhibitors (e.g., Acarbose and Miglitol.

Cardiac disorders and conditions, for example hypertension, dyslipidemia, ischemic heart disease, cardiomyopathy, cardiac infarction, stroke, venous thromboembolic disease and pulmonary hypertension, have been linked to overweight or obesity. For example, hypertension has been linked to obesity because excess adipose tissue secretes substances that are acted on by the kidneys, resulting in hypertension. Additionally, with obesity there are generally higher amounts of insulin produced (because of the excess adipose tissue) and this excess insulin also elevates blood pressure. A major treatment option of hypertension is weight loss. Agents administered to treat hypertension include Chlorthalidone; Hydrochlorothiazide; Indapamide, Metolazone; loop diuretics (e.g., Bumetanide, Ethacrynic acid, Furosemide, Lasix, Torsemide); potassium-sparing agents (e.g., Amiloride hydrochloride, benzamil, Spironolactone, and Triamterene); peripheral agents (e.g., Reserpine); central alpha-agonists (e.g., Clonidine hydrochloride, Guanabenz acetate, Guanfacine hydrochloride, and Methyldopa); alpha-blockers (e.g., Doxazosin mesylate, Prazosin hydrochloride, and Terazosin hydrochloride); beta-blockers (e.g., Acebutolol, Atenolol, Betaxolol, Bisoprolol fumarate, Carteolol hydrochloride, Metoprolol tartrate, Metoprolol succinate, Nadolol, Penbutolol sulfate, Pindolol, Propranolol hydrochloride, and Timolol maleate); combined alpha- and beta-blockers (e.g., Carvedilol and Labetalol hydrochloride); direct vasodilators (e.g., Hydralazine hydrochloride and Minoxidil); calcium antagonists (e.g., Diltiazem hydrochloride and Verapamil hydrochloride); dihydropyridines (e.g., Amlodipine besylate, Felodipine, Isradipine, Nicardipine, Nifedipine, and Nisoldipine); ACE inhibitors (benazepril hydrochloride, Captopril, Enalapril maleate, Fosinopril sodium, Lisinopril, Moexipril, Quinapril hydrochloride, Ramipril, Trandolapril); Angiotensin II receptor blockers (e.g., Losartan potassium, Valsartan, and Irbesartan); Renin inhibitors (e.g., Aliskiren); and combinations thereof. These compounds are administered in regimens and at dosages known in the art.

In a round bottom flask under nitrogen 286 mg (1 mmol) of Compound 256 (ZGN-256), 270 mg (1.16 mmol) of the cinnamic acid derivative, 13.4 mg (0.11 mmol) of DMAP, and 0.22 mL (1.3 mmol) of dissopropyl ethyl amine is dissolved in 10 ml of hexanes. To the stirred solution is added 0.22 ml (1.16 mmol) of pivaloyl anhydride. The reaction is allowed to stir at room temp for 6 h at which point an additional 0.22 ml (1.16 mmol) of pivaloyl anhydride is added. The reaction is allowed to stir over night and the next day the reaction is diluted with ethyl acetate (50 ml) and washed with saturated sodium bicarbonate (20 ml) and dried over sodium sulfate. Purification by flash chromatography (biotage, SiO₂, Methanol/dichloromethane gradient) gives 293 mg of the title compound (58% yield).

Example 18—Compound 461

In a round bottom flask under nitrogen 200 mg (0.7 mmol) of compound 256, 160 mg (0.7 mmol) of the cinnamic acid derivative, 9.3 mg (0.07 mmol) of DMAP, and 0.16 mL (0.91 mmol) of dissopropyl ethyl amine is dissolved in 10 ml of heptane. To the stirred solution is added 0.14 ml (0.7 mmol) of pivaloyl anhydride. The reaction is allowed to stir over night and the next day the reaction is diluted with ethyl acetate (50 ml) and washed with saturated sodium bicarbonate (20 ml) and dried over sodium sulfate. Purification by flash chromatography (biotage, SiO₂, Methanol/dichloromethane gradient) gives 90 mg of the title compound (24% yield).

Example 19

Studies were conducted using 18-20 week old Diet Induced Obese (DIO) C57BL/6 mice. The study was a 7 day screen that included 18-20 week old C57BL/6 mice that were provided a high fat diet for 14 weeks, and treated with compounds injected subcutaneously daily at 0.3 mg/kg. FIG. 1 shows the weight loss of effect of this dose for various disclosed compounds.

Example 20

10 day studies were conducted that included 20 week old C57BL/6 mice on high fat diet for 14 weeks treated with either 10% DMSO or the same vehicle containing an amount of drug to deliver a dose of 3 mg/kg PO (oral gavage) of disclosed compounds for 10 days. ZGN-201 control was dosed at 1 mg/kg PO. ZGN-444 was dosed at both 3 mg/kg and 0.3 mg/kg. FIG. 2A, B, C depicts the 10-day PO efficacy at 3 mg/kg of disclosed compound. FIG. 2C shows 10-day PO efficacy at 3 mg/kg for compound 444 and other disclosed compounds, indicating the oral efficacy of compound 444.

At the end of these studies testes from the mice were harvested, homogenized and digested with endoproteinase Glu-C. The N-terminal peptide of mouse thioredoxin (a selective substrate of the target enzyme MetAP2 was analyzed by LC-MS/MS for full length peptide amino acid 1-6 (SEQ ID NO. 1: MVKLIE), and the degree of detection in a given tissue is indicative of MetAP2 inhibition in that tissue. (See J Proteome Res. 2008; 7:4807). FIGS. 3A, B, and C, show the concentration of SEQ ID NO. 1 (ng/mL) and indicates that certain compounds are not available to the testes tissue as compared to the other tested compounds (and therefore may have fewer testes related side effects). FIG. 3C indicates compound 444 administered orally is not available to the testes tissue.
